F5 Quit to begin a new line on the home screen. There are many uses for a function that is entered in the graphing list. Graphing the function in an appropriate viewing window is one of these. Up to 99 equations can be entered in the.
When you intend to graph an equation you enter in the list, you must use x as the input variable. Because we intend to graph this equation, the input must be called x. Type x by pressing x- VAR or F1 x , not the times sign. TI 85 For convenience, we use the first, or y 1 , location in the graphing list. Enter the right hand side as. TI 86 For convenience, we use the first, or y 1 , location in the graphing list. If any of them are, use until you.
The view you see is — 6. Follow the procedures shown in either 1. Whenever you draw a graph, you have the option of manually changing the view or having the calculator automatically find a view of the graph. We later discuss the ZOOM options. Below yScl is a setting called xRes.
For all applications in this Guide , have xRes set to 1. CLEAR removes the menu from the bottom of the screen if you wish to see more of the graph. This option will automatically find a view to see a l l the functions that you have turned on in the graphing list. Delete all other functions that may be entered in other locations.
Before doing. Set xMin to 0 and xMax to It does. Your calculator automatically sets a vertical view based on the xMin and xMax you set and draws a graph of the function. The x -values shown when you trace depend on the horizontal view that you choose, and the y -values are calculated by substituting the x -values into the equation that is being graphed.
The number 1 in the upper right hand corner of the screen tells you that you are tracing on the equation in y 1. Trace past the edge of the screen and notice that even though you cannot see the trace cursor, x and y values of points on the line are still displayed at the bottom of the screen. Also notice that the graph scrolls to the left or right as you move the cursor past the edge of the current viewing screen. I t is important to realize that such outputs are never exact values unless the displayed x -value is identically the same as the value of the input variable.
If you do not. Your screen may look slightly different. Try it! Draw the graph of y1 in a view containing the input you intend to use. If the input value is not between xMin and xMax , an error message results when you evaluate. Welcome to ManualMachine. We have sent a verification link to to complete your registration.
